Rate of Change of Acceleration given Total Length of Valley Curve Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rate of Change of Acceleration = (Length of Curve/2)^2*Deviation Angle*Design Speed^3
C_a = (L_s/2)^2*N*v^3
This formula uses 4 Variables

Variables Used

Rate of Change of Acceleration - (Measured in Meter per Second) - Rate of Change of Acceleration refers to how quickly the acceleration of an object changes over time.
Length of Curve - (Measured in Meter) - Length of Curve is the distance along the road where the alignment changes from upward to downward slope, creating a valley-shaped concave.
Deviation Angle - (Measured in Radian) - Deviation Angle is the angle between the reference direction and the observed direction.
Design Speed - (Measured in Meter per Second) - Design speed refers to the intended or planned operating speed for a particular section of a roadway or railway.

STEP 1: Convert Input(s) to Base Unit

Length of Curve: 7 Meter --> 7 Meter No Conversion Required
Deviation Angle: 0.88 Radian --> 0.88 Radian No Conversion Required
Design Speed: 5 Meter per Second --> 5 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_a = (L_s/2)^2*N*v^3 --> (7/2)^2*0.88*5^3

Evaluating ... ...

C_a = 1347.5

STEP 3: Convert Result to Output's Unit

1347.5 Meter per Second --> No Conversion Required

FINAL ANSWER

1347.5 Meter per Second <-- Rate of Change of Acceleration
